What is aphthous stomatitis?
Aphthous stomatitis is a common disease characterized by the repeated formation of benign and non-contagious mouth ulcers (aphthae) in otherwise healthy individuals. The common term, canker sores, is also used, mainly in North America, although this may also refer to any mouth ulcer.
The cause is not completely understood, but involves a T cell-mediated immune response triggered by a variety of factors. Different people have various different triggers, which may include nutritional deficiencies, local trauma, stress, hormonal influences, allergies, genetic predisposition or many other factors.
How common is aphthous stomatitis?
Recurrent aphthous stomatitis is the most common oral lesions found in humans. They may occur anywhere but are most frequently found on the buccal and gingival mucosa or adjacent tongue surfaces. It has a frequency rate of 25% and a 3-month recurrence rate as high as 50%.
However, it can be managed by reducing your risk factors. Please discuss with your doctor for further information.
